Isabella deposited $2,000 in an account that pays 5% simple annual interest. After one year, how much interest in dollars and cents will her investment have paid? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
$100
Step-by-step explanation:
Simple Interest formula is given as:
A = P(1 + rt)
Where
A = Amount after t years
P = Principal = Initial Amount Invested = $2000
r = Interest rate in t years = 5%
t = time = 1 year
A = 2000(1 + (0.05 × 1)) = 2100
A = $2,100.00
The Amount after 1 year = $2100.00
The Simple Interest is calculated as
= A - P
= $2100 - $2000
= $100
Therefore, after 1 year her investment would have paid $100
The perimeter of a triangle is 108ft. The sides lengths are in a ratio of 2:3:7. How long is the shortest side?
Answer:
18ft
Step-by-step explanation:
2+3+7 = 12 (this means that 108ft is [tex]\frac{12}{12}[/tex])
The shortest side would be [tex]\frac{2}{12}, or \frac{1}{6}[/tex] of 108ft
To find this, we divide 108 by the denominator (6) to get 18ft
We would usually multiply this by the numerator when finding a fraction of an amount, but as the numerator is 1, the answer would stay as 18ft.

Find a12 in the arithmetic sequence if a1 = 20 and d = 2
Answer:
The value of a[tex]_{12}[/tex] is 42
Step-by-step explanation:
The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common differencen is the position of the term in the sequence∵ a[tex]_{1}[/tex] = 20 ⇒ first term
∴ a = 20
∵ d = 2 ⇒ common difference
∵ We need to find a[tex]_{12}[/tex]
∴ n = 12
→ Substitute them in the formula above
∵ a[tex]_{12}[/tex] = 20 + (12 - 1)(2)
∴ a[tex]_{12}[/tex] = 20 + (11)(2)
∴ a[tex]_{12}[/tex] = 20 + 22
∴ a[tex]_{12}[/tex] = 42
∴ The value of a[tex]_{12}[/tex] is 42

Answer:
Step-by-step explanation:
triangle: a+b>c. If two lengths are put together, and equals more than the length of the third side, then it's a triangle
right triangle: a2+b2=c2 if the square of the two lengths equal the square of the third, then it's a right triangle
acute triangle: a2+b2>c2 if the square of the two lengths are greater than the square of the third it's acute
obtuse triangle:a2+b2<c2 if the square of the two lengths are less than the square of the third it's obtuse
If a line goes through the following two points: (0,0) and (2,1), the slope of the line is:
A. 3
B. -2
C. 1/2
D. -1/2
Answer: m = 1/2
Step-by-step explanation: Let's use the graphing method.
To find the slope of the line using the graphing method,
we first set up a coordinate system.
Next, we plot our two points, (0, 0), which we label point A, and (2, 1),
which we label point B, and we graph our line, as shown below.
Now just graph the line through the two points.
Now, remember that the slope, or m, is equal to the
rise over run from point A to point B.
To get from point A to point B, we rise 1 unit and run 2 units.
So our slope, or rise over run, is 1/2.
Answer: C. 1/2

Give the slope of any line that is perpendicular to the line y = -1/8 x + 5
Answer:
8
Step-by-step explanation:
To find a slope for a line that is perpendicular to another line, you simply need to take the negative reciprocal of the the original line's slope. In this case we are already given the slope as the coefficient to x: -1/8. The negative reciprocal of that is 8/1, or just 8.

if x^2=20, what is the value of x?
a. +_ sqrt 10
b. +_sqrt 20
c. +_ 10
d. +_40
(the +_ is that weird symbol that has the plus sign on top of the underscore, i forget what its called)
Answer:
x = ± [tex]\sqrt{20}[/tex]
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ± [tex]\sqrt{20}[/tex]
which can be simplified to
x = ± 2[tex]\sqrt{5}[/tex]
[ ± means plus or minus ]

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

Which equations have infinitely many solutions?
Answer:
The 1st, 3rd and 4th
Step-by-step explanation:
Answer:
Options B and D
Step-by-step explanation:
Let's solve each equation:
x-3x=-2x+4
-2x=-2x+4
0=4
No solutions, so A is wrong
x-1/3(3x)=0
x-(3x/3)=0
x-x=0
0=0
Infinitely many solutions, so B is correct
1/3x-3=4+2x
1/3x=7+2x
-5/3x=7
x=-21/5
One solution, so C is incorrect
3x+2-1/3(3x)=2+2x
3x+2-(3x/3)=2+2x
3x+2-x=2+2x
2x+2=2+2x
2x=2x
0=0
Infinitely many solutions, so D is correct
x-1/3x+2=0
2/3x+2=0
2/3x=-2
x=3
One solution, so E is incorrect
As you can see, when both sides of the equations are equal to each other such as 0=0 and x=x, you'll always have infinitely many solutions. Therefore, options B and D are correct
Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer
Answer:
no
Step-by-step explanation:
y = -2x + 16
-2 = -2(10) + 16
-2 = -20 + 16
-2 = -4
which is wrong
Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.
y = -2x + 16 > -2 = -2(10) + 16
Now, solve.
-2 = -2(10) + 16 > -2 = -20 + 16 - Start by multiplying out parenthesis.
-2 = -20 + 16 > -2 = -4 - Add.
-2 = -4
The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.
Anybody know the answer
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan38° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex] ( multiply both sides by 14 )
14 × tan38° = x , then
x ≈ 10.9 ( to the nearest tenth )
